Thanks for the heads-up. I was going on what they'd posted. I should go back on the bench if warranty's paying 1 hour for this:

Remove the recliner cover.
Remove the inertia latch from the recliner assembly.
Remove the recliner assembly bolts.
Remove the recliner assembly from the seat.
Install the recliner assembly to the seat.

#395 of 2018 S-10 EGR valve
Feb 17, 2004 (3:41 am)
I've been hearing reports of S-10s with the 4.3 engine having problems with the EGR valve. Does anybody know what the symptoms are?
My 1997 S-10 makes a "rattling" or "pinging" noise briefly at mild acceleration. I'm wondering if it's the EGR valve gone bad, or a PCM problem not controlling the valve correctly. Any thoughts? Thanks in advance.

Takes about 5 minutes to check, but requires the use of a Tech II scan tool. Common problems are the valve pintle hanging due to carbon buildup, and plugged recirculation passages causing low exhaust gas flow. Here are the symptoms:
Exhaust Gas Recirculation (EGR) System Diagnosis
Results Of Incorrect Operation
With too much EGR flow at idle, cruise, or cold operation, any of the following conditions may occur:
The engine stalls after a cold start.
The engine stalls at idle after deceleration.
The vehicle surges during cruise.
The vehicle idles roughly.
If the EGR valve stays open all of the time, the engine may not idle. A DTC P0401 may set. Refer to DTC P0401 Exhaust Gas Recirculation (EGR) Flow Insufficient .
Too little or no EGR flow allows the combustion temperatures to get too high during acceleration and load conditions. This could cause the following conditions:
Spark knock (detonation)
The Linear EGR System Check covers the diagnosis of the EGR system. Refer to Exhaust Gas Recirculation (EGR) System Diagnosis .

...thanks for the info. Like most "home mechanics", I don't have my own TechII tool, however I know someone with the Snap-On equivalent.
I've already checked the pintle valve and EGR passages and they're OK. The drivability is good, so I'm assuming it's something a little deeper. I'll have to contact my "Snap-On friend".
#398 of 2018 poor gas mileage

The only problem I have with my '03 crew cab is the gas mileage It has 10K on it and I am lucky to get 16 on the highway. Is this typical? Love to drive it but my not be able to afford to keep it!!!!

Wow that's low for 16 mpg. Are you sure that your figuring it correctly? I was considering on buying one, but not too sure now.
#400 of 2018 Oil Burning
Mar 22, 2004 (6:39 pm)
I own a 2002 S-10 ZR2 that I bought new. I have 21m miles on it and I have changed the oil and filters 500 1500 3000 5000 and every 3000 miles after that. At around 15,000 miles I noticed that I had lost about 1 quart and a half of oil. I thought it was the garage I brought it too. Anyway after the next oil change I was again about 2 quarts low. I brought it to the dealer, and they changed the PCV valve and told me to come back in 1500 miles. I am still losing oil. I went back to the dealer and they told me to come back in another 1500 miles. When I take the truck on the highway, It is very under powered I have to put the pedal practically to the floor to maintain speed (65) going up hill. Its almost time to go back to the dealer (AGAIN). Does anyone else have this problem or have any ideas of what this may be??

Is your truck a crew cab or is it a standard 2 door? What size engine does your truck have? Is it a standard or automatic? Have you been using more gas since you started having problems with your oil? Do you monitor your gas mileage and can I ask you what it is, before and after?
Mar 23, 2004 (12:56 pm)
Its an extended cab with the 4.3 V6 automatic. Not too sure about the gas mileage. Its not my daily driver so its hard to tell if the gas mileage has changed but I would say I get around 15MPG I don't really notice any difference in that MPG....
Mar 24, 2004 (3:37 am)
...I would find another dealer to look at the truck, as it sounds like you've got a problem lurking in there somewhere.
I have a 1997 S-10 4x4 with the 4.3 engine. Currently I have 45,000 miles on it. I change the oil every 2000 miles, however it doesn't use a drop between changes. With respect to power, it has PLENTY for a V-6. Expressway driving is no problem at all.
I've never carefull checked my gas mileage, but rough calculations put me around 19-20 MPG, with probably 70% of my driving on the highway.
